The important part played by Spring-Rice during the period of the Russian-Japanese War has been known for some time from the correspondence of Roosevelt and from other sources. That he was not only a charming person, but a keen observer and outstanding statesman becomes more evident yet from a perusal of these volumes. In addition to further information on Roosevelt's mediation in the Russian-Japanese War, the reader will find here excellent chapters dealing with conditions in Germany in the late nineties and in Russia in the succeeding years. But of the greatest importance are the sections dealing with Spring-Rice's ambassadorship to the United States from 1913-1917, which are based upon the extensive use of unpublished material. These years covered the critical period of American neutrality and were filled with the tension resulting from British interference with American trade. There can be no doubt that the moderating influence of the English ambassador to Washington was quite as important as the influence of Page in preventing a conflict. These volumes are as interesting and fascinating for the student of American foreign relations as to the reader interested in the history of British foreign policy.
